Title: Pad device for magnetic head
Inventor: HARADA SHINICHI
IPC: G11B17/34
Filed: 1989-03-23
Abstract: PURPOSE:To obtain uniform head touch at inner and outer peripheries by forming the depth of the groove of a groove part for negative pressure generation in a pad device for magnetic head in such a way that an inner peripheral side is always cut deeper than an outer peripheral side against a recording medium. CONSTITUTION:The groove parts 2a and 2b for negative pressure generation are formed on a medium confronting plane in the radial direction of a disk shape recording medium 1, and also, the depth of the groove parts 2a and 2b are formed in such a way that the groove at the inner peripheral side is cut deeper relatively. Since the depth of the groove parts 2a and 2b for negative pressure generation at the inner peripheral side are cut deeper than that at the outer peripheral side against the medium 1 centering a magnetic head, the amount of air that flows in the groove part 2b at the inner peripheral side is increased, and generating negative pressure can be increased. Therefore, it is possible to slide the recording medium 1 with the magnetic head with uniform pressure even at every position extending over from the outer peripheral side to the inner peripheral side. In such a way, satisfactory head touch can be obtained in an entire area in an access direction.

Title: Apparatus for quantitatively emitting high viscosity material
Inventor: WATANABE KUNIHIKO
IPC: B05C11/10
Filed: 1986-03-31
Abstract: PURPOSE:To stabilize the emission of a material within a short time, in turning an emitting gun ON, by applying high pressure into a rearward oil chamber from a high pressure supply circuit at first to acting initial dynamic pressure on a piston. CONSTITUTION:Before a high viscosity material W such as a sealant or an adhesive is emitted from an emitting gun 8, the forcing pressure of a hydraulic piston 11 is set to a predetermined value corresponding to the emitting pressure of the material W. When the emitting gun 8 is turned ON, the pressure of the rearward hydraulic chamber 14 in a hydraulic cylinder 10 is set to pressure higher than set pressure by respective hydraulic pressure control circuits 23-25. As a result, by the action in the vicinity of dynamic pressure of the hydraulic oil supplied from a high pressure supply circuit 50, the material W is emitted from the emitting gun 8 and the flow amount of the material W from the emitting gun 8 becomes constant in a short period and the material can be emitted under stable emitting pressure.

Title: Method for selecting zone according to circuit state in mobile radio communication system
Inventor: FURUSAWA REIKO
IPC: H04W48/06
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To prevent the connecting destination for originating and incoming calls and the busy mode switching destinations from concentrating in a specific zone by reflecting the current circuit state value of a peripheral zone, in addition to the current value of the receiving level as the conditional information for deciding the priorities of its own zone and the peripheral zone and selecting zones, based on these priorities. SOLUTION: The priority relative importance for each conditional information (receiving level, call connection rate and circuit usage rate) is calculated as 'priority relative importance = current state value of conditional information -reference value' (S11). Then the priority value is calculated as 'priority value = priority relative importance × priority index of conditional information' (S12). The priority is decided, based on the total priority value of those conditional information (S13). Thus, the current state is recognized when a factor requiring the selection logic occurs, and a zone that is in matching with the current state and controlled by a base station controller is selected automatically, so that a mobile machine can perform communication and also in matching with the registered condition.

Then a key photographing position 6 is set at the key longitude and key latitude extracted by the part 5. As a result, a fixed difference of information is kept between pictures.
